First,Thanks a lot guys for the responses,It has helped me a lot.When looking at all the different varieties of ram say for example ddr3 tri channel 6 GB total, how important are all the other specs that go with them in regards to noticeable speed differences. Is it worth the price difference say for Patriot Viper Tri Channel 6GB PC10666 DDR3 Memory - 1333MHz versus Patriot Viper Tri Channel 6GB PC12800 DDR3 Memory - 1600MHz.This is almost a $100 price difference at Tiger Direct. I am using this example assuming a CPU and motherboard that can accommodate them and for video editing.Also basically same question in regards to hard drives, buffer memory and spindle speed?
